Abstract
The success of the Semantic Web mainly depends on huge amounts of RDF. However, the majority of data in legacy system are stored and managed in relational databases; the representation of data from relational database to RDF is a great opportunity. We have proposed an approach of transparently exposing legacy relational databases as virtual RDF graph. This RDF graph is dynamically and automatically generated according the user's query requirements. The most advantages of this approach are assuring data consistency between relational databases and RDF and saving storage space. Through experiments, this approach is a feasible solution.
